PLANT PHYSIOLOGICAL ACCLIMATION TO IRRADIATION BY LIGHT-EMITTING DIODES (LEDS)
Acta Horticulturae, 2007LEDs may be a suitable light source for future use as assimilation lighting in protected greenhouse cultivation. LEDs have properties which offer advantages compared to other light sources, but which also raise specific research questions. The narrow band spectrum of LEDs enables manufacturers to produce LED based lightsources specifically suitable for

Is the light emitting diode (LED) an ultimate lamp?
American Journal of Physics, 2000Simple diagrams are used to show the transformation of a thin “slab” of intrinsic semiconductor (direct gap, kelec=khole) from an ideal “flat-band” photopumped recombination-radiation light source into an ultimate lamp, a p–n junction light emitting diode (LED).

Light emitting diode (LED) system for photodynamic therapy
SPIE Proceedings, 1995Photodynamic therapy, PDT, has mainly been done clinically using laser systems. The use of lasers to treat cutaneous lesions is not necessary. In order to provide a more efficient and cost effective light source for the PDT treatment of cutaneous lesions, a clinical based light emitting diode (LED) system has been developed.

Radiative Cooling of Outdoor Light emitting Diodes (LEDs)
2023The coldness of outer space is a huge thermodynamic resource that can be utilized as an infinite heat sink that helps in cooling terrestrial objects without the need for electrical energy through a phenomenon known as radiative sky cooling. In the last decade, radiative cooling has seen an increasing attention as a sustainable and clean cooling method ...

Light-Emitting Diodes (LEDs) for Improved Nutritional Quality
2017Light is one of the key factors in plant production. Phytochemical composition and content as well as nutritional and postharvest quality depend on light quality and quantity in many plant species, especially in leafy vegetables, many of which are grown in controlled environments where artificial or supplemental illumination is needed.
